Description

technical field

[0001] The invention relates to the technical field of stereoscopic display, in particular to a 2D / 3D switchable integrated imaging stereoscopic display device. Background technique

[0002] With the development of display technology, 3D display is developing towards popularization. Compared with ordinary 2D display, 3D display can provide depth information of objects, making viewing more realistic.

[0003] The existing common 3D display technologies are as follows: (1) wearing polarized glasses, the left and right lenses of the glasses are a pair of orthogonal polarizers, and the parallax images of the left and right eyes are respectively displayed with orthogonal polarized light, so the left and right eyes are respectively obtained Corresponding to the parallax image, the brain fusion produces a three-dimensional effect. Due to the need to wear special glasses, the viewing comfort is greatly reduced. Due to the use of polarizers, the utilization of ligh...

Embodiment

[0025] figure 1 It is a schematic diagram of a 2D / 3D switchable integrated imaging stereoscopic display device provided by an embodiment of the present invention. Such as figure 1 As shown, it mainly includes: a backlight unit 00, which is used to generate a backlight supporting 2D display; a side-light type light guide plate 01, which is used to generate a point light source array supporting 3D display (the light source 02 is located on the side of the side-light type light guide 01 ); the switching control unit 04 is used to switch and control the opening and closing states of the backlight unit and the side-light type light guide plate, so that only the backlight unit or the side-light type light guide plate is turned on at each moment; the transmissive display panel 03 is used for according to The switching control results of the switching control unit display corresponding 2D or 3D images.

[0026] Its working principle can be found in the appendix figure 2 with attac...
